In my revision of the North American Eucosminae (Bull. 123. U. S. Nat. Museum, p. 172, 1923) I applied the generic name Exentera Grote to a small group of closely related species including improbana Walker (=cressoniana Clemens) and spoliana Clemens. I did this upon the assumption that, in the main, Fernald and others had correctly identified the Grote species. Although I had gone over the Fernald collection at Amherst, Mass., I did not see the Grote types, and assumed they were in the British Museum and so stated in the revision (p. 174).
